Police in Portland said they have arrested a 29-year-old man accused of running up to a police horse, uttering a “karatelike battle cry” and delivering what a spokesman calls “a jumping, double kick” to the horse’s right thigh. Police said the horse, named Olin, was unfazed and unhurt Wednesday.

A police spokesman noted Olin outweighed his attacker by about 1,000 pounds. Olin and his human partner took Joseph Cruz into custody for investigation of interfering with a law enforcement animal.

The incident happened as mounted officers patrolled Portland’s Old Town, near a bus depot. They had stopped to speak to a group of people.
